RADIATOR-PROTECTOR.

Specification of Letters Patent.

Patented Dec. 5, 1916.

Application filed January 21, 1913. Serial No. 743,407.

To all whom it may concern:

Be it known that we, TALBOT E. Pmnon and Jessie J. KERR, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Radiator-Protectors, of which the following is a specification.

The present invention has reference to radiator protectors for motor cars, and it proposes, in brief, an improved device WhlCll may be applied to one of the pipes included in the cooling system for preventing the water from freezing in and bursting the radiator connected with such system when the car is stationary for long periods and the engine is stopped.

The invention further of the general character a ove specified which may be attached to any engine of conventional type, which may be readily applied and subsequently detached with equal facility when not needed, and which pro oses a device may be manufactured at comparatively low cost in stock size, and added to the equipment of a car with but little extra expense.

With the above and other objects in view, the invention may be said to consist preferably of a heater which incloses the pipe line between the bottom of the radiator and the inlet manifold, so as to set up a circulation of the water, the heat supplied being produced by any suitable agent.

An embodiment of the invention is illus trated in the accompanying drawing, of which Figure 1 is a diagrammatic side elevation of the front portionof a motor car equipped with one form of the improved heater, the bonnet bein partly broken away to disclose the same; Fig. 2 is an enlarged part-sectional side elevation of the heater and the pipe to which it is applied; Fig. 3 is a front elevation of Fig. 2; and Fig. 4 is a view similar to Fig. 2, but showing a modification.

In said drawing, 1 indicates, generally, the engine of the motor car, 2 the radiator, 3 and l the water inlet and outlet manifolds leading to and from the jackets of the engine cylinders, and 5 and 6 the pipe connections or lines between said manifolds and the bottom and top of the radiator. The circulating pump 7 is interposed between the inlet manifold and the pipe 5, and said pump, as well as all of the other parts or elements afore-mentioned, may beof the usual or any preferred construction.

The heater 8, wherein the invention primarily resides, as already stated, is preferably mounted upon the pipe 5, the arrangement being such that when the engine and pump are stationary and the heater is in operation, the water in said pipe becomes rapidly heated and is caused to circulate through the entire system by thermo-si phonic action. the heater, in its preferred form, consists of a substantially cylindrical steel shell or jacket made in two counterpart sections which are provided with marginal flanges 9 'adapted to be bolted together. This jacket is disposed co-axially with the pipe whereon 1t 1S clamped, and its diameter is somewhat greater than that of said pipe, thereby providin an elongated annular or cylindrical cham er 10 between the pipe and the wall of the jacket. At its ends, the jacket is constricted, so as to fit tightly around the pipe, the marginal flanges on the jacket members at these points uniting to form the collars 11.

The jacket itself is heated through the agency of devices ordinarily supplied extraneously of the motor car, and such devices may consist either of a suitable gas or oil burner, or an electric current. In the latter instance, the source of current may be wholly independent of the car, or may be the dynamo included in the electric lighting ancil 90 starting system with which the majority 0 cars are now equipped.

Where a burner is employed to heat the jacket, (Figs. 2 and 3), the latter is provided with a depending tubular member 12, which forms a socket adapted to receive therein the upper end of a frusto-conical deflector 13, this socket being produced, of course, by mating extensions of the jacket sections that are likewise marginally flanged. The deflector, in turn, is arranged directly above the burner 14, which latter, when gas is utilized as the burning fluid, is carried by the supply pipe 15 and is referabl equipped with a mantle 16 and chimney 1 of the ordinary type. flame of the burner thus passes through the chimney into the deflector, and then into the chamber 10 in the heater proper, whence it finally escapes through one or more small vents 18. Virtually the same arrangement is followed when an oil burner is used in place of the gas burner.

As shown in Figs. 2 to 4,

When an electric current is utilized for heating purposes, the heater is furnished with a resistance coil 19 which is disposed within chamber and is connected at its terminals with the Wires 20 and 21 which, in turn, are connected with the source of current supply.

In each of the forms above described, it will be apparent that the portion of the pipe inclosed by the jacket is subjected to dlrect heat, in consequence whereof, the Water will be caused to circulate through the entire system, thus obviating any danger of freezing. Further description of the invention and its advantages are deemed unnecessary in view of the foregoing.

We claim 1.- A device for protecting the water circulating system of internal combustion engines, consisting of a substantially cylindrical shell or jacket adapted to be mounted on one of the Water circulating pipes of such system and to inclose a portion of such pi e, and comprising, in its entirety, a plurality of counterpart, longitudinal sections having continuous marginal flanges adapted to be fastened together; said jacket having a diameter greater than that of the pipe, so as to provide an elongated annular heating chamber between said pipe and the wall of the jacket, and being constricted at its ends so as to fit tightly around said pipe and thereby close the ends of such cham er, the flanges on the aforesaid jacket ends uniting to form collars which tightly encircle the pipe; and

means for supplying a heating agent from an exterior source to the interior of saidchamber, to directly heat the inclosed ortion of said pipe, and to thereby heat an induce a circulation of water in the system.

2. A device for protecting the Water circulating system of internal combustion engines, consisting of a substantially cylindrical shell or jacket adapted to be mounted on one of the water circulating pipes of such system and to inclose a portion of such pipe, and comprising, in its entirety, a plurality of counterpart, longitudinal sections having continuous marginal flanges adapted to be fastened together; said jacket having a diameter greater than that of the pipe, so as to provide an elongated annular heating chamber between said pipe and-the Wall of the jacket, and being constricted at its ends so as to fit tightly around said pipe and thereby close the ends of such chamber, the flanges on the aforesaid jacket ends uniting to form collars which tightly encircle the pipe; and an posed within said jacket to directly encircle the inclosed portion of said pipe, said coil having means for connecting it to a source of electrical current, so as to directly heat the said inclosed portion of the pipe, and to thereby heat and induce a circulation of water in the system. 4

In testimony whereof we have hereunto set our hands in witnesses.
